Follow the steps in this Quickstart guide to get up and running with Akamai Functions in less than two minutes. Akamai Functions is the platform for running Spin applications on Akamai Cloud.

📘

To complete this tutorial you need access to the public preview of Akamai Functions. If you haven’t already requested access, please complete this form. The Akamai Functions team will review your request and follow up shortly.

Install Spin

Spin is an open-source project you can use to build, run, and deploy Spin applications. It's both a CLI tool and a runtime. It provides SDKs for a variety of programming languages, including, but not limited to, Rust, Go, JavaScript and TypeScript.

curl -fsSL <https://developer.fermyon.com/downloads/fwf_install.sh> | bash

sudo mv ./spin /usr/local/bin/spin

To find the Spin version installed on your machine run, spin --version.

Install the aka plugin for Spin

To interact with Akamai Functions, you need to install the Akamai Functions for Akamai Spin plugin, aka. Use this command to install the plugin.

spin plugin install aka

If you’ve previously installed the aka plugin, take a moment to upgrade it to ensure compatibility with the latest features and fixes.

spin plugins update  
spin plugins upgrade aka

You can learn more about managing Spin plugins in this article.

👍

Go to the aka spin command reference for a complete list of supported commands.

Install language specific tooling

With Spin you can build applications using a wide variety of different programming languages. This quickstart, contains instructions and samples for JavaScript, TypeScript and Rust.

Follow these instructions to install language specific tooling on your machine.

👍

Go to, WebAssembly language support matrix for more information about the supported languages.

node --version  
v22.13.0

Create a new Spin application

Next we’ll prepare an application with Spin. There are code samples below for you to use, but you can write an app from scratch or use an existing template. The Spin Hub has many reference examples and templates. You can also find several code samples, sorted by use case in the Akamai Functions GitHub repo.

spin new -t http-js --accept-defaults hello-spin

cd hello-spin

npm install

// For AutoRouter documentation refer to <https://itty.dev/itty-router/routers/autorouter>  
import { AutoRouter } from 'itty-router';

let router = AutoRouter();

// Route ordering matters, the first route that matches will be used  
// Any route that does not return will be treated as a middleware  
// Any unmatched route will return a 404  
router  
    .get("/", () => new Response("hello universe"))  
    .get('/hello/:name', ({ name }) => `Hello, ${name}!`)

addEventListener('fetch', async (event) => {  
    event.respondWith(router.fetch(event.request));  
});

Compile the application

Use the spin build command to compile your Spin app to WebAssembly.

spin build

Building component hello-spin with `npm run build`

> hello-spin@1.0.0 build
> npx webpack --mode=production && npx mkdirp target && npx j2w -i dist.js -d combined-wit -n combined -o target/hello-spin.wasm

asset dist.js 5.93 KiB [compared for emit] [javascript module] (name: main)

webpack 5.97.1 compiled successfully in 66 ms

Test the application locally

You can test your Spin apps on your local computer by using the spin up command anytime. The spin up command starts an HTTP server on your local machine (port 3000 by default) and instantiates and invokes your Spin application for every request sent to the endpoint.

spin up

Logging component stdio to ".spin/logs/"

Serving <http://0.0.0.0:3000>  
Available Routes:  
  hello-spin: <http://0.0.0.0:3000> (wildcard)

📘

If port 3000 is already in use, you could set a different port by specifying the --listen flag. For example, spin up --listen 127.0.0.1:3001.

From within an separate terminal instance, you can use a tool like curl to send an HTTP request to your Spin app

curl -i http://localhost:3000/

HTTP/1.1 200 OK  
content-length: 14  
content-type: text/plain;charset=UTF-8  
date: Tue, 14 Jan 2025 16:10:36 GMT

Hello, Fermyon

You can terminate spin up at anytime, by pressing CTRL+C.

Log in to Akamai Functions

To log in you need access to the public preview of Akamai Functions. If you haven’t already, please complete the Onboarding form. Akamai Functions supports two identity providers, Akamai Control Center and GitHub. If you have an Akamai Control Center account, you can log in using your user ID and password. Otherwise, you need to use GitHub. If both accounts share the same email address, they are automatically cross-linked.

The Akamai Functions team will review your onboarding request and follow up shortly.

👍

Before you log in using your Akamai Control Center or GitHub account information make sure that you complete the following tasks.

• Install the aka plugin for Spin.
• Receive the allow-listing status for Akamai Functions.
• Request and receive access to the public preview.

1. Run the spin aka login command.

spin aka login

2. Click the link displayed in the output from the spin aka login command.

Go to <https://login.infra.fermyon.tech/realms/neutrino/device?user_code=BB-AA>  
and follow the prompts.

Don't worry, we'll wait here for you. You got this.

3. Authenticate using your Akamai Control Center credentials or your individual GitHub account.
4. Once you're logged in you need to authorize the spin CLI to interact with your Akamai Functions account.

Deploy the application

You can use the spin aka deploy command to deploy the application to Akamai Functions.

spin aka deploy

The spin command runs using the Spin binary in your system path. It reads the Spin application definition file spin.toml in the current (hello-spin) directory to know what application to deploy. It will ask you for a name for the application and then it will ask for confirmation that you want to deploy.

Here's an example of a successful Spin application deployment on Akamai Functions.

Name of new app: hello-spin
Creating new app hello-spin in account your-account
Note: If you would instead like to deploy to an existing app, cancel this deploy and link this workspace to the app with `spin aka app link`
OK to continue? yes
Workspace linked to app hello-spin
Waiting for app to be ready... ready

App Routes:
- hello-spin: https://ec8a19d8-6d10-4056-bb69-cc864306b489.fwf.app (wildcard)

You can CTRL+Click on the link in the terminal window to visit the web application you just deployed.

Congratulations, you’ve now deployed your first Spin application to Akamai Functions!
